Focal lesion of ribs. Observer score variation within the ribs due to focal lesion (arrows) superimposed on diffuse marrow infiltration, shown by (a) axial b900 DW MRI, b axial fat-only Dixon and (c) b900 maximum intensity projection (MIP). Diffuse marrow infiltration results in high diffusion signal throughout ribs (a, c) which conceals superimposed focal lesion (arrow a). Fat only Dixon and MIP facilitate focal lesion differentiation (arrows b, c). Note MIP also demonstrates second focal lesion (dashed arrow c)
